Transform GPS tracks to KML with custom styling. Free browser-based converter with no upload required for secure GIS data.

Frequently Asked Questions

Is GPX to KML free to use?

Yes, the track conversion is 100% free.

Does GPX to KML upload my files to a server?

No, the conversion is performed locally with no upload required.

What file formats does GPX to KML support?

Will it preserve timestamps?

Yes, it can map GPX time data to KML TimeSpan elements.

Does it support Strava and Garmin GPX exports?

Yes. GPX files exported from Strava, Garmin Connect, Wahoo, AllTrails, Komoot, Suunto, and all standard GPX-compatible devices are fully supported.

Does the elevation data carry over?

Yes. If your GPX file contains elevation data (most GPS watches do), it is preserved in the KML output as altitude values, allowing Google Earth to display your track in 3D.

Is my GPS data uploaded to your servers?

No. GPX to KML conversion runs entirely in your browser using JavaScript. Your workout data and GPS tracks are never sent to any server.

Can I convert multiple GPX files at once?

Yes. Upload multiple GPX files and each will be converted to a separate KML file, or you can merge them into one using our KML Merger tool.

What file size limits apply?

GPX files up to 50MB are supported. Long GPS tracks (e.g., multi-day touring routes) with tens of thousands of track points convert reliably.
